Independent arrangement structure of side-direction flow-in funnel type water inlet

Abstract

The invention relates to an independent arrangement structure of a side-direction flow-in funnel type water inlet and belongs to a water inlet arrangement structure. A trash rack shaft is fixedly connected with a trash rack pier. A trash rack is fixedly connected with the trash rack shaft. A trash rack bottom plate is fixedly connected with the bottom of the trash rack shaft. An upper opening of a funnel-type contraction section is connected with the lower portion of the trash rack bottom plate. A lower opening of the funnel-type contraction section is connected with an upper opening of a stand face curve section. A lower opening of the stand face curve section is connected with a gate well lower section water inlet. The center line of the trash rack is not consistent with the axis of a water guiding tunnel behind the gate well lower section water inlet. A gate shaft is arranged above a gate well lower section. A gate is arranged in the gate shaft. A maintaining platform is connected above the trash rack shaft. A trash rack opening-closing device and a gate opening-closing device are respectively fixedly connected with the maintaining platform. The independent arrangement structure is simple and stable in structure, safe and reliable in operation, convenient to construct, economical and practical.

Description

technical field [0001] The invention relates to a water inlet layout structure for water conservancy and hydropower projects, and is especially suitable for independently arranging water inlets. The water inlets can be arranged independently in a narrow area, complex topographic and geological conditions, and the inflow direction is inconsistent with the axial direction of the diversion tunnel behind. Background technique [0002] The water inlet is divided into the overall arrangement of the water inlet and the independent arrangement of the water inlet. The overall layout of the water inlet should be compatible with the main building type of the pivot project, such as dam type and river bed type water inlet; the independent layout of the water inlet should choose the corresponding type according to the topographic and geological conditions, such as tower (bank tower) type, bank slope type, Gate well shaft type water inlet. [0003] However, for some projects, due to the...

AI Technical Summary

Problems solved by technology

[0004] The present invention is an independent layout structure of the funnel-type water inlet with lateral flow, which solves the great difficulty in the arrangement of the water inlet due to the very narrow area where the water inlet can be arranged, and the direction of the inflow is inconsistent with the axial direction of the diversion tunnel. question
